The commit a60945fd08e4 ("ALSA: usb-audio: move implicit fb quirks to separate function") introduced an error in the handling of quirks for implicit feedback endpoints. This commit fixes this.
If a quirk successfully sets up an implicit feedback endpoint, usb- audio no longer tries to find the implicit fb endpoint itself.

I seem to have overlooked this one, and will queue it.
BTW, did you hit actually a regression by the mentioned commit? Or is just a theoretical fix?
I am in the process of writing a quirk to support the MOTU Microbook II device. The fix I submitted is necessary for the device to work. I would be surprised if the fix doesn't also fix regressions with other devices that require the implicit fb quirk.
I will submit the rest of the code needed for Microbook II support soon. I mailed this patch first to become acquainted with the linux patch submission model.
Best,
Manuel
